Formula 1’s governing body has formally confirmed Red Bull’s internal combustion engine as the benchmark for the 2026 season following the first two Additional Development and Upgrade Opportunities (ADUO) assessments. The FIA’s announcement, released this week, revealed no changes to homologation token allocations, meaning Red Bull remains ineligible for upgrades while rivals retain limited opportunities.
The FIA’s latest update provided no new details on power unit performance rankings, only confirming the continuation of existing token allocations. Red Bull’s engine remains in the benchmark category, while Mercedes and Ferrari remain between 2–4% and more than 4% behind, respectively. The lack of movement suggests minimal shifts in the engine hierarchy since the season’s start, despite upgrades introduced by Ferrari in Austria and Mercedes’ reliability-focused tweaks.

Red Bull’s position as the sole manufacturer without upgrade eligibility comes with a cost: rivals gain additional cost cap spending and dyno hours for every period they remain within 2–4% of the benchmark. Mercedes, for example, receives a $3 million cost cap adjustment per qualifying period, a provision that has intensified scrutiny of the ADUO system’s fairness. The FIA has acknowledged potential areas for evolution in the rules, but any changes require majority manufacturer support—something Red Bull’s competitors may resist while benefiting from the current structure.
